(Cl. 281-31) I 2 Claims.

This invention relates to a portfolio.

More specifically, the invention relates to a portfolio embodying a loose-leaf binder having a pocket associated therewith in a manner such that the pocket is accessible when the binder is in open position.

A primary object of the invention is` the pro- Vision of a portfolio embodying a loose-leaf binder provided with a flap extending over the entire back of the cover thereof in the provision of a pocket having an opening extending throughout the length of the binder cover when in open position, thereby providing simultaneous access to the binder and the pocket.

A further object of the invention is the pro- Vision of a portfolio of the above noted character wherein the ap is provided with closing means extending substantially throughout its perimeter and the closing means being operable from and toward the folding edge of the binder whereby the mouth of the pocket is closable with an attendant closing of the binder.

A still further object of the invention is the provision of a portfolio of the above noted character which is simple in construction, which pos- H sesses marked utility, and which is capable of being manufactured at relatively low cost.

Other objects and advantages of the nvention will become apparent in the course of the following description, taken in connection with the accompanying drawing, wherein Figure 1 is an inside plan View of a loose-leaf binder provided with the pocket in accordance with a preferred embodiment of the invention.

Fig. 2 is a top edge view of the structure in Fig. l showing the mouth of the pocket open.

Fig. 3 is a top edge view showing the pocket and binder in closed position.

Fig. 4 is a side View of the structure shown in Fig. 3.

Fig. 5 is a section as observed. in the plane of line 5-5 in Fig. 1.

Referring now in detail to the drawing, Va loose-leaf binder is indicated at B and the pocket associated therewith at P.

The binder B preferably, and as shown, is of the well known ring type, but the invention is not limited thereto since the pocket P may well be associated with loose-leaf binders of various other forms, the main consideration being that the I binder include opposed foldable sides and means for releasably retaining sheets therein.

The binder B, as illustrated, includes opposed sides I0 foldable at II about the edges of the back I2.

As is usual in constructions of this 55 kind, the back I2 is provided with an arcuate metallic band I3 having disposed therewithin yieldable means cooperating with the split rings I Il which are openable to admit perforated looseleaf sheets.

In the provision of the pocket P, a nap I5 of any desirable flexible material is suitably secured at its opposite ends and lower edge to the corresponding margins of the binder sides I0 with the flap extending throughout the length of the binder in open position as in Fig. l.

Preferably, the connection of the flap to the margins of the binder sides is through folds or gussets IB for providing greater expansion of the pocket. The terminal edges of the gussets may be secured or adhered to the binder sides inhany desired manner.

The flap I5 is provided with Zipper tapes I1, preferably one for the part of the flap associated with each side of the binder as is illustrated, and the tapes carry the usual fasteners I8.

As is more clearly indicated in Fig. 1, the tapes Il extend a short distance down the binder back l2, as indicated at Il', for accommodating the slider I9 when the binder is opened and for thus maintaining the slider in operative connection with the fasteners. The opposite ends of the tapes may be spaced as at I1 or may, if desired, extend as at I1'.

Since the usual loose-leaf binders are capable of being flexed away from the inside thereof, the mouth of the pocket P may be readily opened as indicated in Fig. 2, and by the provision of the gussets I6 the pocket may be more readily expanded.

With the improved portfolio in the position of Fig. 1 or Fig. 2, access is had to the binder as well as the pocket which latter extends throughout the length and width of the opened sides I0 and back I2 of the binder, thereby providing ample space for papers and sundry articles.

When it is desired to close the pocket and simultaneously therewith the binder, the slider I9 is grasped and drawn along the upper horizontal runs of the opposed tapes I'I, down the vertical runs thereof and thence along the lower horizontal runs to the position in Fig. 4. The binder and pocket are, of course, simultaneously opened by movement of the slider from the position in Fig. 4 to the position in Figs. l and 2.

While in the binder B only two rings I4 are shown, it is, of course, to be understood that the number thereof may be varied and, in fact, other forms of leaf retaining means may be provided within the scope of the invention.

Furthermore, the Zipper tapes may extend only part way around the margins of the flap l5 instead of substantially all the way, as illustrated. The bottom and end edges of the ap may be adhered to the binder sides directly or otherwise and gussets provided at other points for greater expansion of the pocket.

From the foregoing description, it should be readily appreciated that a novel construction is provided by the present invention wherein looseleaves may be carried as usual inthe binder B and leaves or sheets of variable sizes may be carried in the pocket P and, upon closure of the binder, the mouth of the pocket is closed for eiectively retaining the contents therein.

While I have disclosed but a single specic embodiment of the invention, such is'to be considincluding a back and foldable sides pivotally conered as illustrative only, and not restrictive,- the nected therewith, a flap extending over the outer faces of the back and sides, the flap being secured to the opposite free ends of the sides and to corresponding side edges thereof whereby providing a pocket having a mouth extending throughout the combined length of the sides at the other side edges thereof when the binder is in open position, a pair of Zipper tapes secured to the margin of the ap with each tape extending from adjacent the back and around the margin of the iiap corresponding to each binder side, and a slider movable from and toward the back for closing and opening the pocket with an attendant closing and opening of the binder.

2. A portfolio according to claim 1, wherein the tapes terminate in spaced relation adjacent the back at one side edge of the loose-leaf binder and wherein the tapes at the other side edge of the loose-leaf binder extend a short distance along the back for accommodating the slider when the binder is in open position.
